AB 3-way valve, Plumbing the Valve | Trane 1500 CFM, 750 CFM

Installation

Modulating Water Valves (Option) The actuator on the valve is a 24V, 3- point floating valve. The actuator can be easily removed from the valve body by pressing in on the locking tab and rotating the actuator 45° counter- clockwise (See Figure 6a). The 2-way valves are bi-directional flow. The 3- way valves can be mixing or diverting (See Figure 6b).

Note: The actuator must be removed if soldering is being conducted near the valve. High heat may cause damage to the actuator’s plastic body/mecha- nisms.

On applications without the optional, factory installed piping packages, it is important to remove the cartridge as- sembly from the valve body with the provided tool (Figure 7).

Figure 7: Cartridge removal tool

Use the following steps to complete cartridge assembly removal:

1Remove valve actuator.

2Remove the cartridge assembly from the valve body with the en- closed tool.

3Solder the valve in accordance with normal soldering practices.

4Re-install the cartridge after solder- ing by tightening until it bottoms out. The top surface of the car- tridge will be flush with the top edge of the body casting.

Note: Do not overtighten. Maxi- mum torque is 40 in-lb.

5Replace valve actuator and wire in accordance with instructions.

Plumbing the Valve

The valve may be plumbed in any an- gle but preferably not with the actua- tor below horizontal level of the body. Make sure there is enough room around the actuator for servicing or re- placement.

For use in diverting applications, the valve is installed with the flow water entering through the bottom AB port and diverting through end ports A or B. In mixing applications the valve is installed with inlet to A or B and outlet through AB.

Mount directly to the tube or pipe. Do not grip the actuator while making or tightening plumbing connections. Ei- ther hold valve body by hand or attach an adjustable spanner (38mm/1-1/2”) across the hexagonal or flat faces on the valve body. See Figure 8.
